Abstract

The utility model relates to a multifunction combined ruler, which is a drawing tool comprising four straightedges with graduations, four movable hinges and a movable pencil clip. Through dovetail grooves or rectangular through-grooves on the longitudinal centerlines of all the rulers, the four straightedges are connected by the movable hinges into a quadrilateral hinge mechanism which is adjustable and detachable and can be deformed. Capable of realizing multiple functions of drawing parallel lines, triangles, quadrangles, circles, angles, etc., the utility model is a more ideal drawing tool.

Description

Multi-functional convenient combined ruler

The utility model is a kind of novel practical multifunctional drawing tool.

General ruler, set square function singleness drawn some polygonal shapes such as rectangle as many groups parallel lines, arbitrarily angled triangle, trapezoidal, positive rhombus, any length of side at present, and be not very convenient, more can not replace the effect of compasses.

At the above-mentioned weak point of enumerating, the purpose of this utility model is invented a kind of multifunctional convenient chi that above-mentioned functions is an one that collects.

The purpose of this utility model by following by way of realizing.Combination ruler comprises 4 rulers, 4 hinges, propelling pencil folder A chi (basic chi), B chi (upper and lower attachable mechanical stage), C chi are the same with general ruler with D chi (left and right attachable mechanical stage), each chi edge all is carved with the full-length scale, it is characterized in that having a dovetail groove along A chi longitudinal centre line, be convenient to hinges and in groove, move, and can be in groove arbitrary scale position positioning and fixing, the angle table also is carved with in A chi center; B chi longitudinally center line has a dovetail groove; C chi and D chi longitudinally center line respectively have a saturating groove of rectangle, but groove closed at both ends, and the sealing one end be drilled with a circular port, so that drawing circle uses, C chi, D chi one end respectively with A chi dovetail groove hinge, hinges can move in the dovetail groove, screws nut, can be fixed on C chi, D chi one end on any position.Hinges is made up of screw and nut, and the bottom of screw is clipped in the dovetail groove of A chi and B chi the nut turn-knob on the screw of the saturating groove of rectangle that passes C chi and D chi.The saturating groove of the dovetail of B chi by two hinges respectively with the saturating groove hinge of the rectangle of C chi and D chi, hinges can move in the rectangular through slot of C chi and D chi and also can move along the dovetail groove of B chi simultaneously, like this, the quadrangular mechanism that can adjust, change and dismantle of whole combination ruler formation.

Fig. 1 is the schematic diagram of multi-functional combination ruler.The drawing explanation:

1---A chi (basic chi) 2---B chi (upper and lower attachable mechanical stage) 3---C chi (left and right attachable mechanical stage) 4---D chi (left and right attachable mechanical stage) 5---hinges 6---circle center hole 7---angle table 8---propelling pencil folder

Fig. 2 is a kind of form of hinges.The drawing explanation:

1---screw 2---nut

This combination ruler can be realized 9 kinds of drawing effects, enumerates explanation below respectively.

1, parallel lines: make C chi, D chi vertical fixing in the A chi, parallel lines spacing as required, make B chi mobile phase scale position together in C chi and the saturating groove of D chi dovetail respectively, screw fixed by nut, so just can be along A chi, the B chi upper limb one group of parallel lines that draws, many parallel lattice in like manner can draw.

2, draw rectangle: make C chi, D chi on demand between the square vertical fixing in the A chi, the B chi respectively along C chi and D chi rectangle throw groove on demand mobile phase with scale fix, required rectangle like this can draw along the inner edge of 4 rulers.

3, parallelogram, positive rhombus: at first according to the length of side requirement of parallelogram or rhombus, combination ruler is pressed the adjustment of picture rectangle method, rotate C chi and D chi then and make itself and A chi angle conform to the angle requirement of parallelogram or rhombus, fixed hinge is along 4 chi inner edges required figure that draws.

4, trapezoidal or arbitrary quadrilateral: according to the length on trapezoidal four limits, selected corresponding scale is fixed on each chi of combination ruler, along 4 chi inner edges required trapezoidal or quadrangle that draws.

5, triangle: unload the B chi, require or limit, corner, arm of angle angle, the angle arm of angle require to make C chi, D chi to intersect, along A chi, C chi, the D chi inner edge arbitrary triangle that can draw according to Atria bar edge lengths.

6, draw circle: unload the C chi, insert in the circle center hole of C chi, according to the big or small mobile propelling pencil folder of radius, and fixing, rotate the C chi with a pencil of cutting or the object that has aciculiform, just can draw need circle.

7, fan-shaped: unload the B chi, move the C chi along A chi dovetail groove, make the center of circle graduation mark correspondence of two chis, fixed hinge is drawn radian according to the fan-shaped required length of side.

8, draw the angle: unload the B chi, mobile C chi makes the center of circle graduation mark on the C chi overlap with the angle table vertical line of A chi, fixing hinges, and along the draw one side at angle of C chi, the required angle line of the rotation C chi aligning another side at angle that draws again.

9, combination growth chi: the B chi is separated from the C chi, rotate C chi, D chi and B chi respectively, make 4 chis form the fastening then hinge of straight line.

This chi adopts lucite, also can adopt other metal or nonmetallic materials to make, and this multi-functional combination ruler cost is low, simple in structure, easy to use.

Claims

1, a kind of multi-functional combination ruler, belong to drawing instrument, it is characterized in that: this chi is made up of 4 rulers, wherein A chi (basic chi) longitudinally center line have a dovetail groove, the B chi (on, following attachable mechanical stage) longitudinally center line has a dovetail groove, a C chi and a D chi (left side, chi moves right) longitudinally center line respectively open a saturating groove of rectangle, a propelling pencil folder is arranged in (closed at both ends) and the groove, can be up and down, and be drilled with a circle center hole according to drawing circle or fan-shaped big or small fixed hinge C chi and the lower end closed place of D chi, the pencil that insertion is cut had both become centre point.4 rulers of combination ruler can be along dovetail groove or rectangular channel displacement, and 4 fixing hinges are connected into 4 rulers the quadrangle linkage that can adjust, change, dismantle successively.
